How to replace a dishwasher electronic control board

By Lyle Weischwill
How to replace a dishwasher electronic control board

This repair guide gives step-by-step instructions for replacing a dishwasher electronic control board. The electronic control board runs all the dishwasher's functions—filling, washing, drying and draining—which can make it difficult to pinpoint the control board as the source of a problem. Refer to the tech sheet for diagnostic tests (it's usually behind the service panel below the door) or have a local dishwasher repair expert test the dishwasher electronic control board. If the electronic control board is faulty, replace it with a manufacturer-approved replacement part.

These basic instructions will help you replace the electronic control board in many Kenmore, Whirlpool, KitchenAid, Maytag, JennAir, Amana, GE, Frigidaire, Electrolux, LG and Samsung dishwashers.
